Direct proof of use
Army Recognition reported in an early-2017 survey of Soviet-made armored vehicles in the Syrian conflict that Syrian governmental troops had BTR-152, BTR-60, BTR-70, and BTR-80 armored personnel carriers in their APC inventory, and that some tracked BTR-50 carriers had been issued to mechanized infantry.
The source supports a Syrian-government conflict-use claim, but it does not identify a specific unit, battle, vehicle serial, or loss incident. The safest catalog reading is therefore that BTR-50s were fielded as tracked mechanized-infantry troop carriers in government service, not that they formed a large or heavily documented frontline fleet.

Inventory and wartime context
Pre-war and early-war order-of-battle references show why the type was available for wartime issue. INSS listed Syrian ground-force APC holdings in a January 2013 Syria file, grouping BTR-40, BTR-50, and BTR-60 vehicles together and noting that the figures represented the Syrian order of battle before the outbreak of the civil war. GlobalSecurity similarly listed BTR-50s in the Syrian army equipment table while warning that totals did not reflect combat attrition during the ongoing civil war.
Bellingcat's open-source review of Syrian Arab Army armored-vehicle losses describes the war's heavy attrition of government armor and says the Syrian army had other BTR-series APCs on paper, while many were obsolete and of limited combat value. That broader loss study helps frame the sourcing limit: public, visually confirmed loss records emphasize tanks, BMPs, and other tracked systems more than BTR-50s.

Battlefield role
The BTR-50 was a tracked amphibious armored personnel carrier built around a PT-76-derived hull and designed to move infantry under light armor protection. In Syria, the documented conflict role was mechanized-infantry transport for the government side, alongside a larger inventory of Soviet-origin armored vehicles.
No reliable public source found for this record identifies BTR-50s as transferred into Syria during the civil war, used by opposition forces, or used in a specific named operation. The evidence supports possession and fielding by Syrian government forces rather than a detailed incident chronology.
